I have seen this happen so many times in the US. The last time it happened, we were at dinner with a bunch of our colleagues. Somehow the discussion drifted to the concept of arranged marriages and how "elders in the family" can decide the wedding. While I was stoically trying to defend how these weddings are actually "arranged", another junior of mine (obviously, Indian) was actually enjoying the whole episode and spicing it up by giving more and more instances of "marriage-in-10-minutes". He even said that his parents had not seen each other until the wedding day etc etc etc. After he brought his parents into the discussion, however, I could not say more.
Later though, I gave him a piece of my mind without holding back. Always remember, others will respect you, only when you respect yourself.
